Factoring a real value of cargo in port investment and funding decisions

Ports are marine gateways to economic activities. Ports’ ability to perform services depends on their facilities, harbor conditions, and other factors. Generally, ports have control over their facilities but must compete for funding to improve them. As for waterways, in the U.S., a Harbor Maintenance Trust Fund was established to fund dredging, which levies a 0.125% cargo value tax on most shippers using U.S. coastal and Great Lakes harbors. Yet, commonly, a gross tonnage metric is used to allocate the fund’s resources, resulting in under-maintenance of some harbors. This, reportedly, deters additional port funding and hinders valuable commerce. Supplemental economic metrics, such as value of commerce or cargo, can improve port financing decisions, but such data is not readily available. Container ports collect cargo value data in nominal terms, but bulk ports do not. When making economic decisions, however, real values must be used. Further, when allocating resources, decision-makers must be able to assess ports over time and relative to each other. Conforming to these criteria, this paper develops three port financing indicators based on a real value of cargo and illustrates their calculations using the U.S. Port of Duluth-Superior as a case study.     

An empirical study of the impacts of operating and market conditions on container-port efficiency and benchmarking

Despite the growing amount of research on container-port efficiency and benchmarking, the literature on the subject is yet to provide stable and consistent results across researchers and in relation to dynamic operating and market conditions. In this paper, we formulate a number of operational hypotheses to test the sensitivity of benchmarking results to port market and operating conditions namely production scale, cargo mix, transhipment ratio, operating configurations, and working procedures. A series of data envelopment analysis (DEA) models are used to measure the operational efficiency of 420 container terminal decision-making units from 2004 till 2010. The results show that variations in operating conditions highly impact terminal efficiency and that future work on container-port performance and benchmarking should take into account the structure and mechanisms underpinning the operations of container ports and terminals.

滨州港海域泥沙运动遥感图像分析

通过滨州港所在海域的卫星遥感图像分析,揭示了在不同条件下海域的含沙量分布特征和泥沙的运动规律,并对其形成的原因进行了初步的分析。结果表明,滨州港海域的含沙量总体是比较高的,近岸区比邻近的黄骅港海域含沙量还要高。海域含沙量受风浪影响较大,涨落潮时在东北风作用下海域含沙量比较大。从泥沙运动的角度而言,受已建导堤影响,落潮水流和风吹流、波生流等叠加可能形成较复杂的向外水流和环流,携带泥沙向外输运,使高含沙水体运动更远的距离,一般情况下可达-6 m等深线以远。

洋山港疏浚土资源化利用探讨

位于杭州湾湾口北侧、上海市东南方的崎岖列岛,由数十个小岛组成,是离上海市最近的拥有深水岸线的岛屿群。依托于崎岖列岛建设的洋山港,是一个通过（东海）大桥连接于大陆的典型离岸海港,由于毗邻多水多沙的长江口且当地潮汐强度大,港内水体以含沙量高、流速大为主要特点,因而预期营运后港口存在大量维护性疏浚土需处理的问题。文章结合港口平面形态、疏浚部位与强度和可持续发展的要求,拟从适宜的维护疏浚方式、泥土处理的环保要求以及港内适宜布置泥土处理的条件等方面,提出洋山港疏浚土资源化利用方案。     

青岛港铁矿石物流发展研究

随着世界经济区域化、国际化、一体化的发展,以港口为中心的现代物流日益成为区域经济发展的"动脉",进而成为区域经济发展的"龙头"。2001年以来,青岛港提出建设区域性航运中心、发展港口物流的发展战略,本文正是以此为背景而进行的。青岛港已经具备了发展港口物流的各种良好优势和条件,建设铁矿石物流中心的前景看好。

天津港重大工程建设中水动力泥沙问题研究

基于天津港近些年来重大工程项目的建设,利用物理模型、数学模型及现场实测资料分析等科研手段,对天津港深水航道的建设、南疆港区的扩建、南北防波堤的延伸及东疆港区海岸一期工程的建设,进行了一系列的试验研究。(1)天津港海域开挖建设深水航道从自然条件方面是可行的;(2)海河口北治导线南移,使两治导线间距由1900 m缩为1200 m。既能满足泄洪要求,又能扩大南疆的用地面积;(3)防波堤延伸至16+0,港内的流态及泊稳均能满足设计要求,可使天津港减少60%的淤积量;(4)试验结果对东疆港区东海岸一期工程人工沙滩的冲淤稳定性、港内的水体交换等,提出了优化措施。
